Abstract :

In view of harmful effects caused by synthetic antibiotics in treating bacterial infections in human beings many studies were carried out to find some alternative methods using safe and natural plant products. In the present study Methanolic extracts of twenty plant species were evaluated for their anti microbial activity against twelve selected bacterial human pathogens by well diffusion method. out of twenty plant extracts evaluated six of them namely Tribulus terrestris , Sphaeranthus indicus, Euphorbia hirta, Hyptis saveolens Tagetes patula, have shown significant anti bacterial activity against eight tested pathogens which are Staphylococcus aureus, Pseudomonas aurigenosa, Streptococus pneumoniae, Eschericia coli, Streptococcus pyogenes, Klebsiella pneumonia, Citrobacter koseri.
